Radio replacement adapter cable with built in CANbus ignition and speed pulse interface for Porsche cars with original CDR24 or PCM2/2.1 audio systems. These cars have ISO connectors at the back of the head unit.

Porsche ISO to ISO radio replacement adapter harness.Built in CANbus ignition interface that gives a key present ignition supply to the new radio. It also gives out a speed pulse signal for use when installing a navigation radio. The speed pulse output can be changed to other CANbus output signals such as reverse gear and handbrake, see the instructions for more details.

This harness is designed to give CAN ignition, it will also give audio in cars that have speaker wires in the original ISO connector. There is an amplifier turn on wire on this harness, this is for cars that have a non Bose amplifier that receives a normal speaker level audio signal from the head unit.This harness will not retain audio in cars with Bose audio systems as there is no speaker outputs at the head unit, these cars will have a fibre optic connection from the head unit to the amplifier, a different interface is required. This adapter cable does have spare power, ground and ignition wires, this allows for easier installation of the additional Bose fibre optic interface.

Please Note: The spare red, yellow and black wires are used for a fibre optic system.
